M5 Globular Cluster

This is the M5 Globular Cluster in the constellation Serpens. I recently acquired an ASI294MM mono camera for my RedCat 51 telescope setup. This is an interesting camera in that it has a bin 1 mode were the pixel size is 2.3um and the resolution is 8288 x 5644. This puts it nicely inside the range for my RedCat 51 so my final image is not under sampled. I use bin 1 mode for my L filter and then bin 2 on RGB. I upscaled the RGB images and then combined for the final shot.

I've not done very much in terms of LRGB post processing. I'm quickly finding there is almost too much information on this subject. I subscribe to Adam Blocks tutorials as well as I've viewed a few of the hundreds of tutorials on YouTube. I'm figuring things out... all be it slowly. M5 is actually a nice starter object for this as there is not too much that can go wrong. I like globular clusters and in the future I would like to do some spectroscopy on them if possible. M5 has a number of RR Lyrae variable stars which could be interesting especially if I use my C14 OTA. Anyway, this is just more on my learning curve for astrophotography.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
